Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you. The surging is an indication that your carburetor is starving for fuel at idle speed. Did you soak your carburetor prior to cleaning?
Thanks for this information. Did you use a small wire to clean the small jet and fuel passages inside the body of your carburetor?
Does your engine surge at higher speeds?
If you hold the throttle on your carburetor, with your hand, will surging go away, or continue?
If the surging continues, this indicates that you still have a partially clogged jet, or fuel passage, although you have cleaned your carburetor. Have you checked to see if your fuel shut off solenoid is fully opening?
If it was replaced last season, then it is likely ok, if you can hear it click. Was your carburetor fuel bowl dirty, before you cleaned it?
Remove your fuel hose from your carburetor, then turn your key to start position, to spin your engine. Watch to see if you are getting a good flow of fuel to your carburetor. Catch your fuel in a suitable container. If you are getting fuel to your carburetor, then your carburetor is still our problem.
You are very welcome! No problem. Also, spray some carburetor cleaner around the area where your carburetor mounts to your intake manifold. Let's see if the surging changes.
I look forward to knowing your results, on tomorrow. Thanks!
Thank you for checking. Due to the fact that you are getting fuel to your carburetor, and you do not have air leaks between your carburetor and intake manifold, I am lead to believe that your carburetor is still at fault, although you have cleaned it.
